Carved and machined aircraft aluminum. From one piece of aircraft aluminum. Conceptual design of this piece started for me in 10th grade. I was unable to work out the design, so put it away, took it out again 15 years ago, then again in earnest 2 years ago, and finally was able to complete the design in October of 2014. The first 4 attempts to make it were unsuccessful, finally got it though. The surface is engraved with a dense series of lines, giving an iridescent pattern, reflecting light and color in a very pleasing way. Curiously, looks best from across the room in dim light. One of my signature pieces. A smaller pair of this design sold at my first show immediately upon show opening, it was then that I knew I was on to something. Configured as a wall hanging, it also rests in various positions on a horizontal surface, for example a fireplace mantel.
